The nightly rendition of “Sweet Caroline” following the seventh inning was just a little bit sweeter on Opening Night at Fenway Park.

Singer/songwriter Neil Diamond made a surprise appearance during the Red Sox’ season opener against the Yankees on Sunday night, belting out his hit “Sweet Caroline” as the Fenway faithful sang along.

Wearing a dark sports jacket with the message “Keep the Dodgers in Brooklyn” written on the back, the 69-year-old Brooklyn native connected with the fans who regularly use his song as a late-inning rallying cry.
